DVD looks horrible on LED flatscreen

Thanks for any help on this. Have been making DVD's w/ DVDSP for years... always looking great on computer and various players. Just tested on a Samsung LED 40" and it looks horrible, unwatchable, pixelated, blurry. Unfortunately, this is where the DVD will be screened. Have tried various TV settings and can't figure out the problem. Have a deadline for viewing and I'm in a bit of a panic...any advice appreciated. Thank you!

I don't mean to be a wet blanket, but if the same DVD is looking good (or better) on other monitors, then I would suspect the presentation monitor, and its ability to play standard definition source material correctly.


Have you gone through the setup menu on the monitor? I know some monitors have MPEG artifact filters, that reduce the apparent compression artifacts - but soften the image in doing so.

But when I try to use the 7.0 as the average bit rate, it moves the max to 8.3. I'm getting an error from DVSP saying that bitrate is too high.

That indicates that your video is too long for that bitrate. In reviewing this thread, I see that is something i didn't;t ask about before suggesting 7 Mbps. If it's longer than about an hour and a quaarter, you'll have to adjust the slider until the indicated time allowance is above the run time of the video.


One other thing I noticed is you indicate field dominance as Upper. The DSLR's shoot true progressive, which is what should be showing in that box. I'd go back to your FCP project and check your sequence settings.


Finally, since you found that your previous DVDs also had some issues, I would agree with MtD and revisit the the equipment explanation. I remain curious about the role of the player in all this. Should be easy enough to swap out.

The clip I've been playing with to get this right is just 2 minutes. That's why I was surprised to get that error message from DVDSP.


My FCP sequence settings show "none" for field dominance. There is no option for progressive.


All the different flavors of HDTV's have jolted me out of my comfort zone. Everything had been looking good for so long on the standard def TV's when playing DVD's. So this process has been great and I appreciate your help.


Here's what I'm working with now and seeing a lttle bit of improvement. The piece has gone from unwatchable to decent looking...still not super crisp. Please let me know if there is anything else I should tweak to get this looking as good as possible. I used to use Bitvice and am wondering if you think that would help improve things.

Thanks.

Hppy to hear you're making progress.


None in FCP is correct fpr progressive.


This latest summary does indicate progressive, while the first one (5.5 Mbs) indicated interlaced (upper).


I don't understand the DVDSP warning either. I tried a test @ 8.5 without it complaining.


Have you tried a different player yet?

Was able to redo all my files, export HQ, which I think made a difference and then encode with some of the new settings suggested. It definitely looks better, although not perfect. But I will definitely try a new player as recommended. The commercially produced DVD's look good using this older player, though. Do you think, using this equipment and these settings, this is the best I can do? Thanks for all your help with this.

little late to the conversation but...


In compressor try changing your GOP to "IP"


User uploaded file

From the Compressor Manual


  • IP: No B-frames are used with this setting. Choose IP only if your media contains fast motion that isn’t encoded with sufficient quality using an IBBP or IBP structure.
  • IBP: One B-frame is used between reference frames (I-frames and P-frames). Choose this setting only if your media contains fast motion that isn’t encoded with sufficient quality using an IBBP structure.
  • IBBP: Use IBBP for the majority of MPEG-2 encoding situations, along with a GOP size of 15 for NTSC, or 12 for PAL. Two B-frames are used between reference frames with this setting.



Hope this helps

Hi Tony,


Thanks for your input. I'm still working on this issue. Just upgraded the player...and that's just a tad better, but am interested in your advice. Could you please explail what this means and how you feel it will help. I'll go ahead and try it, but I also want to understand this better. Thanks!

Rylie,


I have just been through the same and to understand this issue it is helpful to understand the following

  1. Progressive vs interlaced vision
  2. Frame rates and shutter angles in camera
  3. Progressive vs interlaced televisions
  4. How mpeg compresses vision and the purpose of the I, P and B frames
  5. DVD players, each handles the upsizing of SD to HD TV differently, the newer ones typiclly doing this better. The cabling used on a player will make a difference, composite, component or HDMI, composite only handling interlaced vision.


Rylie, there are so many variables and unfortunately these topics are a little to lengthy to cover here, besides there are many far more knowledgable people out there who have written on these topics in depth. I would suggest a search on each and reading some on each as, frustratingly, they all affect the end result.
